1.Txhua qib twg ntawm "corrosion" puas muaj nyob hauv ib puag ncig?
Kev tiv thaiv qis: kev tiv thaiv yooj yim, ib txheej zinc nyias yog txaus
Nruab nrab rau cov khoom lag luam tsawg: nruab nrab zinc txheej, tiv thaiv anti - Cov corrosion
Nruab nrab corrosion: thicker zinc txheej, tiv taus cov pa paj tawg
High corrosion Kuj: Tuab Zinc Txheej Deg + Nto Kho, tiv taus cov tshuaj tsuag / muaj pa tso pa
Tsis tshua muaj neeg ua xeb zoo: ntxiv tuab zinc txheej + txheej, muaj zog corrosion tsis kam
2.Qhov xaiv hom galvanizing txheej?
Kub - dip galvanizing (GI): Cov ntawv steel yog raus hauv Molten Zinc los ua ib txheej zinc los ua ib txheej zinc kom ua rau fickness thiab zoo nkauj nplaum). Lub zinc txheej ua ib qho kev ua kom tiv thaiv anode los tiv thaiv cov ntawv hlau thiab haum rau cov chaw sab nraum zoov (C5).
Cov piv txwv suav nrog cov ru tsev ru tsev, tsheb chassis, thiab sab nraum zoov nkhaus.
Electrogalvanizing (Zin Txheej yog muab tso rau hauv electrolysis (nyias tuab thiab muaj kev sib haum xeeb). Nws corrosion kuj yog weaker dua kub - dip galvanizing thiab tsuas yog tsim nyog pleev xim rau kev tiv thaiv sab hauv tsev.
Piv txwv suav nrog cov cuab yeej siv hauv tsev thiab cov khoom siv ntsuas ntsuas.
Galvanizing Alloy (GA): Tom qab - daim ntawv kho thiab cov ntaub ntawv kub} Nws corrosion tsis kam yog qis dua GI, tab sis nws yog kos {{{{{ove}}} istant thiab haum rau cov ntaub ntawv sib cuag, xws li lub cev tsheb (C3-C3).
3.Qhov xaiv cov tuab ntawm galvanized txheej?
Lub thickness ntawm zinc txheej yog qhia raws li "Tag nrho Zinc cov ntsiab lus ntawm ob sab (G / M²)". Lub thicker txheej txheej, lub ntev dua lub neej (nyob rau hauv tib qho chaw, doubling zinc txheej thickness tau txuas lub neej los ntawm 1.5-2 zaug).
4.How tuaj yeem siv cov kev kho deg ua kom tau siv los txhim kho corrosion tsis kam thiab siv?
Hla: Tom qab galvanizing, ib qho chromate lossis chromium- rustivation txheej (haum rau corrosion resistance lub sij hawm (haum rau C3-C4 ib puag ncig).
Kev kho roj: Qhov saum npoo yog coated nrog anti - Rev Roj los tiv thaiv ib ntus Nws yuav tsum tau muab tshem tawm ua ntej siv (haum rau luv-} kev tiv thaiv nyob rau txhua qhov chaw).
Xim txheej: ib qho xim organic (xws li txheej txheem polyester lossis haum rau C4-C5 ib puag ncig corrosive, xws li ntug dej hiav txwv lub tsev).
5. Dab tsi yog cov kauj ruam xaiv?
Txheeb xyuas qib ib puag ncig corrosion: raws li cov av noo, salinity, thiab paug, txiav txim siab seb ib puag ncig tau faib raws li C1-C5.
Txiav txim siab hom galvanizing: kub - dip galvanizing (GI) yog qhov kev xaiv rau cov ntawv thov sab hauv tsev yooj yim.
Phim rau Zinc Txheej Thickness: Xaiv cov ntsiab lus zinc kom tsim nyog raws li qib corrosion (piv txwv li, z275 lossis siab dua C4).
Cov kev kho cov txheej txheem ntxiv: passivation los yog xim txheej tuaj yeem siv los siv txhawm rau txhim kho corrosion tsis kam nyob rau hauv ib puag ncig corrosive heev.
Raws li kev ua lag luam: Rau cov qauv ua kom tiav, xaiv qhov tob -} kev kos duab zoo li DX53D; Rau kev ua tiav yooj yim, xaiv qib qib xws li DX52D.
